If f(x)=x2-x, what is f(-5)

Answer:

x = 12

Step-by-step explanation:

9x - 20 - 4x = 40

Combine like terms

5x -20 = 40

Add 20 to each side

5x -20+20 = 40+20

5x = 60

Divide by 5

5x/5 = 60/5

x = 12

9x - 20 - 4x = 40

By transposition method, we get

9x - 4x = 40 + 20

By simplifying the like terms, we get

5x = 60

or, x = 60/5 = 12

The value of x is 12.

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y-k=a(x-h)^2[/tex]

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

It's been given the vertex of the parabola as (-2,18):

[tex]y-18=a(x+2)^2[/tex]

Now substitute the point (-5,0) and find the value of a:

[tex]0-18=a(-5+2)^2[/tex]

Operating:

[tex]-18=a(-3)^2[/tex]

[tex]-18=9a[/tex]

Solving for a:

[tex]a = -18 / 9[/tex]

a = -2

Thus, the equation of the quadratic function is:

[tex]\mathbf{y-18=-2(x+2)^2}[/tex]

I took 42 divided by 72 times 100

Answer:

A

Step-by-step explanation:

Assuming you mean the square root of five, then the answer is A.

You start by taking the square root of both sides.

√(x - 4)^2 = ±√5

x - 4 = ±5

x = 4 ±5

7 three-course meals

Step-by-step explanation:

7 x 15= 105

141-105= 36

36/12= 3

7+3= 10

So total, there are 10 meals; 7 three-course and 3 two-course

Answer: C (0,0), (-4,0) and (0, -5)

Step-by-step explanation:

After repositioning the triangle, the vertices will be A(0, 0), B(0, -5), and C(-4, 0). This new positioning will make the coordinate proof easier since the coordinates are now simpler, and one vertex is located at the origin, which often simplifies the calculations in coordinate geometry proofs.

To make a coordinate proof easier, it's helpful to reposition the triangle in a way that simplifies the calculations and coordinates. In this case, you can reposition the triangle by translating it so that one of its vertices aligns with the origin (0, 0). This process is known as translation.

Let's reposition the triangle so that vertex A(5, -2) aligns with the origin (0, 0). To do this, we need to subtract the x-coordinate of vertex A from all the x-coordinates of the other vertices and subtract the y-coordinate of vertex A from all the y-coordinates of the other vertices.

The new coordinates for the repositioned triangle will be:

A(5, -2) -> A(0, 0) (remains the same, as it aligns with the origin)

B(5, -7) -> B(5 - 5, -7 - (-2)) -> B(0, -5)

C(1, -2) -> C(1 - 5, -2 - (-2)) -> C(-4, 0)

Determine the reflected image in the x axis

When a point is reflected across the x axis, the x coordinate remains the same, while the y coordinate is negated.

In other words,

[tex]A(x,y)[/tex] when reflected becomes [tex]A'(x,-y)[/tex]

So, for each of the following points

[tex]A = (- 1, 8)[/tex]

[tex]B = (-8, 8)[/tex]

[tex]C = (-5, 1)[/tex]

There images are:

[tex]A' = (- 1, -8)[/tex]

[tex]B' = (-8, -8)[/tex]

[tex]C' = (-5, -1)[/tex]

B and $684

Step-by-step explanation:

B, because wednesday is three days after sunday so 4 times 3 because she walks 4 more laps each day until saturday. Add the 24 laps she already walks 4(3)=12+24=36

By saturday she would've walked 48 laps, so 48 times 3 for the 3 dollars each lap. 48(3)=144 now u have to find the other days so the equation you would use is 3(24 + 4x), x for the day until saturday. 3(24+4(1))=3(28)=84,just do that for each day and then add all them together because the question asked by the end of the week, saturday, how much money so yea. 84+96+108+120+132+144=684

(honestly u could just keep adding 12 to the previous number as that's what it's increasing by.) haha rlly hope I'm not wrong on the second one. Have a nice day!
